New Calibration Menu
Valid from firmware version 846003-001, a new calibration menu and method have been
introduced in the Oxix converter.
A factory calibration of both zero point and span has been made at delivery; these calibrations can
be done independently of each other. It is not usually necessary to calibrate. We recommend
checking the zero position every 6 to 12 months.
The calibration is saved in the converter and you will need to conduct a new calibration if the
sensor is moved to another converter.
We recommend conducting a factory reset of the sensor before conducting a new calibration, since
you avoid that any errors in an existing calibration affect the new calibration.
We have also added a menu with the possibility of adjusting salinity levels in the measurement.

A zero point check or calibration is conducted as follows:
• The sensor is set for a zero point solution. The current measurement is shown in line 2
(0.10mg/l in this example).
• Set the desired measuring value on the first line using the up and down arrow keys.
• Save the current measurement setup by pressing OK.
The value is saved in the converter and will correct the measurement value of the sensor.
